No it isn't necessary. The Honda and Yamaha are the best. Don't get one till you have spent time on the boat and know the answer as to whether it is worth getting one for you.Is it necessary to purchase a portable generator? If so, which would be the best? I heard Hondas are pretty good
Ah yes where we get even less solar hours and where most boats reside only on moorings.....:winkMaine-you live in Maine. I think you mostly cruise N.E. Think that has impact on your (quite educated) choices.
If I had to respond to Outbound's post it would have been exactly the same as yours.We like our Honda. Great for charging batteries when the solar cannot, when we need relief from the heat to put one AC on and run the odd 120 volt equipment. My Honda cost me $800 back on 2008. One can be had for about $1200 now. Inboard diesel generators cost upwards of $10,000-20,000 to put one in. Do the math.
I'll add carbon monoxide as very real hazard to contend with as well. But if you're not in marina may be only reasonable way to run power tools.
